Somebody else has already mentioned this, but intermittent fasting has been a game changer for me. The usual way to start doing it is what's called 16/8, which means that you have a feeding window of 8 hours, in which you're allowed to eat, and you fast for the remaining 16 hours of the day. You're free to choose when the window starts. Some people even go further and do 20/4, skip entire days or do OMAD, which stands for one meal a day. I feel like 16/8 is the sweet spot, though.

I started with a 12pm-8pm schedule, but I work evenings and was often cheating a little bit because I had trouble being consistent about dinner timing. So I changed things around and now I start at 7-8am, and it's been much easier.

There's some literature that indicates that IF provides several other health benefits, but if your main goal is to lose weight, it can help in the sense that, with an 8-hour feeding window, you'll naturally end up skipping one meal, normally either dinner or breakfast. That'll definitely make a dent on your caloric intake, if you're disciplined and eat healthy stuff for your remaining meals. As most other comments have pointed out, there's no secret for losing weight: it's calories in < calories out. Putting that into practice consistently is the hard part!
